Fall River, also known as Lazy Lake, is a gravity dam located in Columbia, Wisconsin, along the North Branch Crawfish River. Completed in 1859, this dam serves primarily for recreational purposes, providing a serene setting for water enthusiasts to enjoy. With a height of 17 feet and a length of 300 feet, Fall River has a storage capacity of 900 acre-feet, with a normal storage level of 578 acre-feet.

Despite its age, Fall River maintains a satisfactory condition assessment and is inspected every two years to ensure its safety. However, due to its high hazard potential and very high risk assessment, the dam's management team must remain vigilant in implementing risk management measures. The dam features a controlled spillway with a width of 60 feet, capable of handling a maximum discharge of 3000 cubic feet per second.

Fall River's location in the beautiful Wisconsin countryside, paired with its historical significance as one of the oldest dams in the area, makes it a noteworthy site for both water resource and climate enthusiasts. As a regulated structure under the supervision of the Wisconsin Department of Natural Resources, Fall River continues to play a vital role in the local ecosystem and provides a valuable resource for the community to enjoy and appreciate.
